Starting from the mathematical structure of Taiji, the Two Modes, Four Images, and Eight Trigrams in the Book of Changes, this article systematically explores the information-carrying capacity of Bazi and Qimen Dunjia as divinatory systems. Through analysis of Yin-Yang, the Five Phases, the Hetu and Luoshu, and other classical mathematical foundations, it seeks to provide a unified perspective for measuring and comparing the information volume of these two arts.

A thorough exploration of the principles behind Qimen Dunjia's capacity for 'multiple judgments from a single chart.' Through holographic cosmology, multidimensional coordinate systems, the symbolic system of universal correspondences, and the shifting of Taiji focal points, this article dissects the core mechanisms of what is regarded as the highest art of divination in ancient China.

'An in-depth analysis of the core differences between the "Life Chart" (Mingpan / Zhongshen Pan) and the "Hourly Chart" (Shi Pan / Shijia Qimen) in Qimen Dunjia. Exploring from the dimensions of temporal scope, analytical logic, application range, and philosophical essence, this article reveals the dialectical relationship between fate and contingency in Yixue divination.'

This essay undertakes an in-depth study of the 'Yi' ode from the Greater Odes (Daya) section of the Classic of Poetry (Shijing) through the lens of pre-Qin thought. It examines the philological origins of the character 'yi' (restraint), confirms Duke Wu of Wei as its author with 'self-vigilance' as its guiding purpose, and elucidates the poem's emphasis on dignity, virtue, its critique of King Li's misgovernance, and its enduring political philosophy and moral cultivation significance.

This article offers a thorough analysis of the core proposition in Xunzi's 'Jiebi' (Dispelling Obscurations) chapter concerning the nature of cognition: 'How does a person know$33 Through the mind. How does the mind know$34 Through xu (openness), yi (unity), and jing (stillness).' It systematically elucidates the dialectical relationship among these three concepts, their epistemological significance, and their roots in high antiquity, revealing the systematic rigor and precision of pre-Qin cognitive theory.

This article undertakes an in-depth exploration of the proposition 'nourishing the will by emulating the numinous turtle' (yang zhi fa ling gui) in the Guiguzi, examining the symbolic significance of the turtle in high antiquity, the wu-xi shamanic tradition, turtle-shell divination culture, ritual status, and longevity philosophy from multiple dimensions, revealing the profound philosophical thought and methodology of spiritual cultivation it embodies, and striving to restore its original meaning within the pre-Qin intellectual context.
